There is a JSON RPC endpoint eth_chainId, https://github.com/ethereum/EIPs/blob/master/EIPS/eip-695.md It's implemented by the major clients Geth, Classic, Parity, Besu, Quorum and in Ganache... Happy to submit a PR

To resolve I had to add the following to settings.gradle ``` pluginManagement { repositories { mavenCentral() gradlePluginPortal() maven { url 'https://dl.bintray.com/hotkeytlt/maven' } } } ```
